The invention relates to connections and has speclal reference to means-for tapping a waste line into a main sewer pipe. I It is well lmown" that plumb'ng'ordinances frequently require that if there is no Ysc'onnection found in the mainsewer where it desired to connect a waste lin'e from a house or the like that a Y-joint must be inserted. The work, ofapplying ,a v'standard' type of 10 Y-joint is difficult and tedious and the'result is that the requirement has been Withdrawn in a great manycities, leaving it to the judgment of theplumber as to how the connection may be made. The usual planis to tap a hole, insert the spigot end of ashort f'section ofpipe and continuewith successive sections or lengths to build up the waste'line. -l The great objection to this is that :if the pipe happens to extend into the sewer pipe, that is project beyond the inner surface. or periphery thereof, it causes an" obstruction against which matter may subsequently accumulate and interferewith the proper flow through t Y rurel showing a'modificationw-herein the waste line is to enter thesewer.

' It is withthe above facts in viewthat I have devised the presentinvention which has for-its general object the provision of a novel t mg-the letter A designates a sewer .pipeof device adapted to betapped or-c'onnected into the sewer'pipeand to receive the waste line.

An important objectoi thein'ventionisto provide means of this character which while havingv a @portion projecting into an open-- ing in the sewer pipe is provided with means whereby it-will be held inzproper position thereon and prevented from displacement in any direction. on I A more specific objectof the inventionis to provide a saddle 'memberfadapted toconformingly engage against the sewer pipe and formed with a portion entering an opening therein; and additionally provided with a socket to receive the end of the wastepipe to Still another object is to provide a saddle member of this type which, may be formed in such manner as to facilitate positive s ecuring and scaling in place so that any possible'leakage of the joint will be avoided; =1

7 Still another object is to provide a connection of this character which though capable of. being made of any desirablewmaterial is I well adapted to be constructed of terracotta orthe like and to be secured in place simply V bymortar or cement. I

- An additional object of the invention is to provlde :a device ofsthis characteriwhichwill be extremely simple and inexpensive to make,

It 1s m- -tended that the curvature of. this saddle memher be such as to conform to that of the pipe ;A' upon which it is to be used so that itmayc L lie in close engagement therewith: when applied. 'At its underside this saddle member is formed with a boss or projection 11 adapted'to be received with a loose fit within a a and claimed, and illustrated in the accom- 5 hole 12 which must be outwithin the sewer pipe at the location whereit-is-desired to connect the waste pipe B- with it. It is pref- To the attainment of the foregoingand In using the device, the hole 12 is first formed in the pipe A at the desired point and the saddle member isapplied with the boss or projectionll received within the opening 12. It is intended that this boss be of no greater thickness than the wall of the pipe'so that it will not project beyond the W inner surface to cause an obstruction. The

pipe Bis engaged within the socketor counterbore 15 and as it rests against the shoulder 16' it will be held in place and cannotproject into the pipe. The parts are then easily secured together as by means of cement. Successive pipe sections are thenassembled and continued from the section B toform the waste line, or any other equivalent methodof construction may be followed. I

If desired, the-underside of the saddle member maybe formed with a groove 17 spaced from its periphery for the reception of mortar or cement indicated at '18, this being an added refinement which might be omitted in some casesor if preferred, though it is of advantage on accountflof making a more perfect seal between the saddle member and the sewer pipe. 7

In=the above described form of the invention it will beobserved that the waste line enters the sewer pipe at right angles thereto. In many instances this may not be desirable and may actually be prohibited, the require- 'ment being often that the waste line must enter obliquely. To take care of this situation Imay resort to the modification shown in Figure 3 wh erein the connection is so formed asfto have the effect of a Y-joint. Referring tothis figure in detail, it will be observed that-the principle isfthe same, the saddle member l0 'being provided at its underside with a projection 11 received within a hole -12*- in the sewer pipe. The saddle member has the jupstanding portion formed with a hole or bore 14? communicating with arecess, counterbore or socket 15, there being a shoulder 16 at the juncture thereof. The pipe study of the drawing it will beapparent that 'terial. inany desired size depending upon the diameter of the sewer pipe and also that of the I have thus provided a very simple and inexpensive connection which may be easily applied particularly as it is not necessary to have a close fit of the projection 11 or 11" within the hole 12 in the pipe. Such a hole may be easily formed in a cement, concrete or terracotta pipe by chipping it away or by "other means. It is apparent that the saddle member lends itself readily to formation from terra cotta or other plastic ma- Of course the device may be made waste line to be tapped thereinto. It is believed that the construction, operation and advantagesshould be readily apparent to one'skilled in the art without further explanation. I

While I have shown and described the preferred embodiment of the invention, it should be understood that the disclosure is merely an exemplification of the principles involved as the right is reserved to make all such changes in the details of construction as will widen the field of utility andincrease'tlie adaptability of the device provided such changes constitute 'no departure from the spirit of the invent-ion or the scope of the claims hereunto appended.

Having thus described the invention, I claim: a
